Hello. My names Dan. I have a bad 350tbi in a 95 k1500. Looking at swapping to a 350 vortec. What would i need to modify to make it work?

You would have to change the engine & computer system. Vortec intake will not bolt on a 1995 5.7. I know, I built a true roller Vortec motor for my 1995 Silverado.

Maybe I read the question wrong. To put a hole vortec engine in, either have to have the obd2 wiring harness and computer to run the motor, it takes 4 02 censors in the exhaust, and an EGR bung inlet in the exhaust. Or do what I did, I bought a new intake, (plus other things you wouldn't need) that is for the 1995 set-up but bolts to the vortec heads. then you can hook your motor up the way it was, and your computer (obd1 computer) will run it.

Danny Did you ever finish your project ,? Because I have everything you need power plant drive train including electric systems complete .If interested text to muddjohn60@gmail.com easy fixins best of luck.
